From the "first road" to "fourth level", why can Cheng and Chong reach?

Today, 70 years ago, the Chengdu -Chongqing Railway, 505 kilometers in length, was officially opened to traffic. This was the first railway built in my country after 1949.

Time is like an arrow. In the past 70 years, the railway connected to Chongqing and Chengdu has developed to the Chengdu -Chongqing Railway, the Chengrui -Chongqing Railway and the Chengdu -Chongqing high -speed rail.

As of the end of 2021, the national railway business mileage has reached 150,000 kilometers, covering 99%of more than 200,000 population cities. The high -speed rail operating mileage exceeded 40,000 kilometers, covering 95%of 1 million people in cities.

In a new round of competition in railway construction, the Chengdu -Chongqing region, which has been promoted to the "fourth pole" of the country, is still at the forefront.

As the Chinese high -speed rail opened the "350" model again, the Chengdu -Chongqing high -speed railway with the Chengdu -Chongqing Railway has become one of the five lines that are the first to realize the normalization of 350 kilometers per hour, and the only one in the western region.

The fourth passenger passage in Chengdu -Chongqing Jian, the Chengyu Middle Line in the construction, has been given the expectation of breaking the speed of "ceiling" that breaks through the speed of China's high -speed rail.

From the establishment of the "New China Road" to leading the speed of China's high -speed rail, from "Shu Dao Difficulty" to "Fourth Pole", why can Cheng and Chong reach?

Implement "first step"

"Erlai is 48 thousand years old, not with Qinsai's smoke." The ancient Shu land trapped by the mountains and mountains has a long history for breaking the traffic constraints.

As early as 1903, the Qing government intends to build the Sichuan -Han Railway, which is located in Chengdu via Chongqing to Hankou. In 1936, the National Government established the Chengdu -Chongqing Railway Engineering Bureau, which began to be built the following year, but soon stopped working due to the outbreak of the Anti -Japanese War in July 1937. Until 1949, the project had only 14%of the project volume, and the railway was not paved.

When the end of the hundreds of wastes, the Chengdu -Chongqing Railway finally entered the reality from her dream.

"The first step to build a new southwest is to build the Chongqing Railway. The economy must be developed and the railway should be first." In January 1950, Deng Xiaoping pointed out in a report to the Central Committee of the Communist Party of China.

Soon, the "Building into the Chongqing Railway" was approved. On June 15, 1950, the Chengdu -Chongqing Railway was officially opened. It opened to traffic on July 1, 1952. In just two years, it was built in the railway that was not built in the previous half century.

Overlooking from the air, the Chengdu -Chongqing Railway is like a "Iron and Steel Dragon" crossing the Sichuan Basin. It starts in Chengdu in the west.

The arrival of this railway has changed the history of Sichuan traffic occlusion, which greatly shortens the time and space between Chengdu -Chongqing: the travel time of the two places, from the previous shiplinks for one week and a car dealer for 2 days to about 13 hours.

The greater significance has been made clear before the construction of the Chengdu -Chongqing Railway: "Chongqing and Chengdu are the central cities in the Southwest. For example, the Railway can drive the prosperity of Sichuan and even the southwest, and provide high -quality rice, pork, poultry eggs and Differential foods have no interoperability; Chinese people have never been designed and constructed by themselves. If the Chengdu -Chongqing Railway is the first to be repaired, it can not only improve China's international reputation, but also make large and small factories be sufficient and accelerate industrial development. "

"As soon as the train sounds, gold is two thousand." As the "First Road in New China", the influence of the Chengdu -Chongqing Railway is far more than one domain.

After the Chengdu -Chongqing Railway was opened to traffic, the freight rate decreased sharply, and the logistics became more unblocked. More than 1,200 Southwest specialty products that could not be transported in the past began to be shipped to East China, North China and other regions. Over the place.

It can be said that the Chengdu -Chongqing Railway has profoundly changed the traffic pattern of Sichuan and even southwest, and has begun the prelude to the large -scale economic construction across the country.

Later

The timeline was allocated to the high -speed rail era, and the high -speed rail connected to Chengdu has once again reached the forefront of the country.

At the end of 2015, the Chengdu -Chongqing high -speed railway was opened to traffic, and the first 300 -kilometer -speed high -speed rail was ushered in the southwest. At the end of 2020, the Chengdu -Chongqing high -speed railway was increased to 350 kilometers per hour. The shortest railway travel time between the two places also compressed from 78 minutes to 62 minutes.

Looking at the whole country, there are currently only 5 high -speed rail lines operating at 350 kilometers per hour. It is worth mentioning that, in addition to the Chengdu -Chongqing high -speed rail, the other four are related to Beijing. Wu section.

However, the seemingly leading high -speed rail "transcript" in Chengdu -Chongqing area has actually experienced twists and turns.

The construction of high -speed rail was backward. 2009 was the key node of the "explosive" development of the high -speed rail. This year, the world's longest and fastest high -speed railway -Wuguang High -speed Railway was officially opened. However, the Chengdu -Chongqing high -speed railway only started the construction of the Chongqing section in 2010, and it was opened to traffic at the end of 2015.

Another example is up to 10,000 high -speed rail. As early as 2015, which was opened to traffic in Chengdu -Chongqing high -speed rail, this high -speed rail had begun to plan, and has been included in the "Medium and Long -term Railway Network Plan" issued in 2016. However, during the "Two Sessions" in the country in 2016, the Sichuan delegation suggested that it will not be able to take the same as the "Thirteenth Five -Year Plan" railway construction plan. In 2020, with the launch of the construction of the Shuangcheng Economic Circle in Chengdu, high -speed rail construction also ushered in a large -scale "outbreak".

In July of this year, the Chongqing high -speed railway Sichuan -Chongqing section was initially designed and was approved by the National Railway Group. The research report of the 10,000 -high -speed rail can be jointly approved by the National Railway Group and the Chongqing Municipal Government. In the beginning of 2022, the Research Report on the Ankang to Chongqing Section of the West Chongqing High -speed Railway was also approved by the National Development and Reform Commission.

In other words, within a year and a half, the Chengdu -Chongqing area has been approved by 5 high -speed rails with a design speed of 350 kilometers per hour.

Prior to this, whether it was the Chongqing high -speed railway that had been opened to traffic inside Sichuan and Chongqing, or the Chenggui and West Cheng high -speed railway outside Unicom, the design speed was only 250 kilometers per hour. It was not until the end of 2020 after the “Da Sui” operation of the Chengdu -Chongqing high -speed railway, and Sichuan and Chongqing had the first high -speed rail at a speed of 350 kilometers per hour.

"Fourth Extreme" rise

In the country's perspective, Chengdu -Chongqing's weight is getting heavier.

In February 2021, the "Outline of the National Comprehensive S three -dimensional Transportation Network Planning" officially positioned the Shuangcheng Economic Circle of Chengdu -Chongqing region as the "fourth pole" in the national comprehensive three -dimensional transportation network, and the Beijing -Tianjin -Hebei, the Yangtze River Delta, Guangdong, Hong Kong, Macao Bay Area side by side.

It is particularly worth mentioning that as the first new trunk railway in the "Shuangcheng Economic Circle Multi -level Rail Transit Planning of the Chengdu -Chongqing District", the high -speed rail of the Chengyu Middle Line is 292 kilometers in length. The fastest high -level high -speed railway, "design speed 350 km/h, reserved 400 km/h".

In fact, for a high -speed rail with a total length of less than 300 kilometers, the operating speed has been increased from 350 kilometers to 400 kilometers per hour, and the savings have limited travel time. Is it necessary to build another high -speed rail between Chengdu and Chongqing, which has also been controversial.

However, from the perspective of many people in the industry, the high -speed rail of the Chengyu Middle Line has an important "test value". Dai Bin, President of the Sichuan Provincial Regional Economic Research Association, pointed out that the important mission of the Chengyu Middle Line high -speed rail is "the task of undertaking the technical standard and management method of high -speed railway at 400 kilometers per hour."

The high -speed rail network has continuously encrypted and accelerated. The 70 -year -old Chengdu -Chongqing Railway did not withdraw from the historical stage. Instead, it has new value -under the blessing of the "fourth pole", the Chengdu -Chongqing Railway is an important in the new land and sea channel of the country. The component and the road to the south -direction line, the volume of freight has risen year by year.

In 2021, the Chengdu -Chongqing Railway cargo sent a total of 3.866 million tons and a total of 2.12.21 million tons of goods. It mainly focused on coal and steel, supplemented by people's biological materials such as food, petroleum, and fertilizer, covering the main production and living materials.

The perspective has been further enlarged, and the railway has also become a major arteries that are open west to south and towards the world.

On June 30, with a column full of electronic products, mechanical parts, daily department stores and other goods, China -EU trains (Chengdu -Chongqing) slowly sailed out of the Chengdu International Railway Port. Listing. Chengdu -Chongqing joined hands has become the earliest, most stable, and influential areas of the China -Europe trains.

Chengdu -Chongqing painting circle, transportation first. In the past 70 years, the railway has not only supported regional development, but also promoted opening up to the outside world. Facing the future, the "Shuangcheng Economic Circle on the Rail" is accelerating, and the "fourth pole" blueprint also has more imagination.
